Verification
Based on the style guide and datasheet for this part, three independent electronics engineering experts created:
- 3 versions of the symbol and 2D footprint
- 1 version of the 3D STEP model (STEP format AP-214)
- A colour palette configuration for a manufacturer
All created library files are layer-mapping agnostic and can be easily mapped to your design.
Created symbols and footprints are then compared using the following checks:
Symbol
Automated Checks
- Part number
- Key parameters
- Package code
- Pin names/numbers
- Pin types
Manual Checks
- Pin organization per style guide
Footprint
Automated Checks
- IPC standard
- Silkscreen clearance
- Courtyard excess
- Package outline
- Polarity marking
- Pad size & position verification
3D STEP Model
Manual Checks
- Dimension verification
- Colour palette compliance
- Format compliance
- Mapping orientation to 2D footprint
- Position verification to 2D footprint
A final verification process is performed:
If symbols and footprints match: The part is verified as ECAD Ready
If symbols and footprints don’t match: A Senior Electronics Engineer will review all differences to ensure the part meets the style guide and datasheet requirements
